Application med iebruary 24, 1913. Serial No. 750,232.

' b all whom it may, concern:

ed a certain new and useful Improvement in Grourid-Anchors, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawlugs, forming part ofthis specification, in which- Figure 1 is a vertical sectional viewthrough my improved ground anchor. Fig. 2 is a top plan view of thesame. i

This invention relates to new and useful improvements in ground anchors,the object being to construct a device of the character described whichmay be of letaehable units whereby the size of the anchor may beincreased or diminished according to the holding power required.

In the drawings, 1 indicates the rod which extends to or above thesurface of the ground, and to which is connected the guy rope or cable.This rod has a not on its lower end by which it is connected to thesection 2 of my improved This section 2 is preferably in the form of thefrustuni of a cone and is provided with an: outwardly extending-flange 2at its base The sides of the cone are provided with projections or lugs2".

3 indicates a. tapered ring having an inwardly extending flange 3 atitsupper edge, said flange having notches 3 which are designed to registerwith the lugs 2 of the section and by slightly turning the section 3,locking the same against longitudinal displacement to the lower edge ofsection 2. Section 3 also has an. outwardly extending flange 3 at itslower edge and lugs 55 for the purpose of codper ting with the notchedflange of the next 5 1'. ;n. of increased diameter as shown in thedrawing. There is also shown in the drawing another section 5.

Additional sections of gradually increasing diameter can employed untilthe desired base diameter of the anchor is secured. In practice, I havefound that the majority of ground. anchors used range from 'Z to 13" indiameter and inpractice the top unit or and notches on said ringsect-ions,

section 2 would preferably be made 7" in diameter across the bottomwhereby this single unit could be employed for ground anchors of thissize. To increase the size of the anchor, a tapered ring would besecured to the top unit or as many rings as would be found necessary tosecure the required diameter. v y

It will be observed when a single unit is employed or a plurality ofunits are used,

that my improved anchor is tapered or is essentially conical in shapehaving shoulders or projections in the form of steps, which shoulders orprojections add materially to the holding power of the anchor. v.Inpractice, after the hole is dug, it is usual to tamp stones in aroundthe anchor, the upper portion of the hole being filled in with dirt. Thestepped shoulders engaging the stones not only offer great resistingpower against a pull on the rod, but the conical shape tends toforce'the stones laterally, and this wet ging action also offers greatresistance to dislodgment of the anchor. i

it can be shipped collapsed and occupy-"'5' very small space, or whenquantities are packed for shipment, the various sizes of rings may benested one within the other so as to occupy little space in hipment.

What I claim'is: 1. As a new article of manufacture, a

"ground, anchor comprising a series of tapered ring sections which aregraduated in size so as to form a hollow conical body when properlyassembled, which ring be readily assembled or taken apart to vary thediameter and height of the anchor, nu

sections can means comprising coiiperating projections for bolding thesame in open position.

2. As a new article of manufacture, a ground anchor, the main bodyportion of which is composed of a series of collapsible members, each ofwhich comprises a ta ered ring section, an inwardly projecting ange onthe upper edge of each section, there being a notch formed in saidflange,'an outwardly projecting flange on the lower end of each section,an integral projection on each sectionadjacent to the flange on thelower edge thereof, which projection is adapted to I tapered ring 10Wtruncated conlcnl 5 connected to the upper tepofthe next i1 ringsections, to said holl sectlons 111 pass through the notch. in theflangeat the djncent sections to lock said open pesition, a holmemberdetachably one ofthe series of and an anchoring rod attached w COIllCfllmember.
